Before You Begin - One for All EXTENDER A1 FOR URC-7780 Instructions Manual

"Almost Clean" installation. This method preserves any device setup codes that you have
•
installed through downloads of internet or phone upgrades but it overwrites all other setup
information. As with a clean installation, it enables you to plan your setup of the extender from
scratch.
Upgrading an existing installation. This method allows you to choose which features of your
•
existing setup you wish to preserve in the extended remote. Not everything can be preserved, but
you can choose any or all of devices, device labels, device code upgrades, key moves and the
volume lock device. Indeed, the only feature available in the extender that cannot be preserved is
Key Macros, for reasons explained in Appendix 2. This is certainly the most flexible installation
method but it needs particular care, as it is easy to carry forward errors from the existing setup to
that of the extender.
It is likely that you will want to set up your extended remote in a way that is very different from your
existing setup for the unextended remote. Indeed, if this were not the case then you would probably see
little point in installing the extender. In this case you should choose a clean installation if your present
setup does not include any device codes from internet or phone upgrades, or an "almost clean" installation
if it does include such upgrades. If, however, you have put a lot of effort into creating key moves ("Key
Magic") that you want to retain with the extender, then you may prefer to upgrade your existing
installation.
If you have already installed an extender on your remote, so are making a re-installation, your choice is
slightly different. If you have saved your original unextended remote setup as a .ir file, you may of
course re-upload it to your remote and use any of the above methods. If you no longer have a .ir file for
an unextended setup then you can always make a clean installation, exactly as if it were an unextended
remote. If you can exit the extender – for this extender the exit procedure is described in section 11 –
then you can also make an "almost clean" installation and preserve any internet or phone upgrades. At
least, you can if your existing extender is this one, success is not guaranteed if it is a different one. What
you cannot do is the third choice above, a general upgrade that preserves other setup data.
Be prepared for some unusual steps in the installation procedure. These are a result of incompatibilities
between the two remotes and the current version (7.15) of IR.exe that are explained in detail in Appendix
2. If you plan a clean, or almost clean, installation then these details need not concern you as they are
taken care of by the installation methods. If you plan to upgrade an existing installation then you must
read Appendix 2, Preparing to Upgrade an Existing Installation, as you will need to take care of these
incompatibilities yourself, before commencing the upgrade, by following the instructions given in that
appendix.

2.2 Before you begin

Before you do anything else, you need to copy the two RDF files that are included in the extender
package into the same folder as your other RDF files used by IR.exe. For the URC-7781 these files are
11311131 (URC-7781 Digital 12).rdf
and 113A113A (URC-7781 Extender A1).rdf.
For the URC-7780 they are
10621062 (URC-7780 Stealth 12).rdf
and 106A106A (URC-7780 Extender A1).rdf.
You probably already have in that folder an RDF file for your unextended remote. Please move this to
another folder to preserve it and then copy both files as explained above. This is important as it ensures
that the RDF files for the unextended and extended remote are mutually consistent. After you have
installed the extender, you should have no further need for the RDF file for the unextended remote. You
